Extract ZIP files — without uploading them anywhere
ZIP is the archive format everyone eventually meets — email attachments, exported reports, bulk photo downloads, old backups. This tool opens ZIP files entirely in your browser: drop one in and every file inside appears as its own download, with folder paths preserved so you can see exactly where each file lived. Extraction is powered by libarchive, the BSD-licensed library behind macOS’s own built-in archive handling, compiled to WebAssembly so it runs on your device instead of a server. That distinction matters for ZIPs in particular, because they so often contain the sensitive stuff — contracts, statements, photo backups, tax paperwork. Nothing you drop here is transmitted anywhere, and once the page has loaded, extraction keeps working even with your internet connection switched off.
How it works
- Drop a .zip file below, or click to pick one.
- Every file inside is listed with its path — download the ones you want.
- For archives with more than a few files, use “Download all as ZIP” to grab everything at once.
Frequently asked questions
Is my ZIP file uploaded to a server?
No. The archive is opened by libarchive compiled to WebAssembly, running inside your browser. The file is read from your disk, parsed in your browser’s memory, and never transmitted. You can confirm this in your browser’s network tab — or disconnect from the internet after the page loads and extract anyway.
Can it open password-protected ZIPs?
Not yet. Encrypted archives are not supported in the current version — a password-protected ZIP will fail to extract rather than prompt you. For those, you will need a desktop tool for now.
What happens to folders inside the archive?
The folder structure is preserved in the file names: each extracted file is shown with its full path (like photos/2019/beach.jpg), so nothing gets flattened or mixed together and you can tell identically-named files apart.
Is there a limit on archive size?
No fixed limit. Because everything runs on your own machine, the practical ceiling is your device’s available memory. Typical ZIPs — even ones with hundreds of files — are no problem on an ordinary laptop or phone.
